Shingles . Shingles is a re-emergence of a the chicken pox virus. It pops up along a single nerve and creates a painful, red rash that is often in a line (along the course of the nerve). The rash usually has yellow bubbles (vesicles) surrounded by redness. There are meds to make it go away quicker and prevent chronic pain in the affected nerve. There is also a vaccine if you are over 55.
